  • Annotated Checklist of the Fish Species (Pisces) of La Réunion, Including a Red List of Threatened and Declining Species
    Stuttgarter Beiträge zur Naturkunde A, Neue Serie 2: 1–168; Stuttgart, 30.IV.2009. 1 Annotated checklist of the fish species (Pisces) of La Réunion, including a Red List of threatened and declining species RONALD FR ICKE , THIE rr Y MULOCHAU , PA tr ICK DU R VILLE , PASCALE CHABANE T , Emm ANUEL TESSIE R & YVES LE T OU R NEU R Abstract An annotated checklist of the fish species of La Réunion (southwestern Indian Ocean) comprises a total of 984 species in 164 families (including 16 species which are not native). 65 species (plus 16 introduced) occur in fresh- water, with the Gobiidae as the largest freshwater fish family. 165 species (plus 16 introduced) live in transitional waters. In marine habitats, 965 species (plus two introduced) are found, with the Labridae, Serranidae and Gobiidae being the largest families; 56.7 % of these species live in shallow coral reefs, 33.7 % inside the fringing reef, 28.0 % in shallow rocky reefs, 16.8 % on sand bottoms, 14.0 % in deep reefs, 11.9 % on the reef flat, and 11.1 % in estuaries. 63 species are first records for Réunion. Zoogeographically, 65 % of the fish fauna have a widespread Indo-Pacific distribution, while only 2.6 % are Mascarene endemics, and 0.7 % Réunion endemics. The classification of the following species is changed in the present paper: Anguilla labiata (Peters, 1852) [pre- viously A. bengalensis labiata]; Microphis millepunctatus (Kaup, 1856) [previously M. brachyurus millepunctatus]; Epinephelus oceanicus (Lacepède, 1802) [previously E. fasciatus (non Forsskål in Niebuhr, 1775)]; Ostorhinchus fasciatus (White, 1790) [previously Apogon fasciatus]; Mulloidichthys auriflamma (Forsskål in Niebuhr, 1775) [previously Mulloidichthys vanicolensis (non Valenciennes in Cuvier & Valenciennes, 1831)]; Stegastes luteobrun- neus (Smith, 1960) [previously S.

Frequently, these are found in museum collections catalogued as immature stages, this being the case for the species reported here. Independent collecting efforts in the Peruvian Amazon and Venezuelan Orinoco as well as a revision of material already available in museums has resulted in the recognition of at least five different species of tiny catfishes, that were identified either as heptapterid juveniles or in the slightly more accurate cases as Imparfinis juveniles. Nonetheless, a detailed morphological study revealed that they represent fully mature individuals, easily assignable to the Nemuroglanis subclade of Heptapteridae, but not to Imparfinis or to any other available name in that family. Morphology of the pectoral girdle and fin exhibits striking contrasting conditions between males and females, and along with modifications of the most anterior ribs, also indicate that they constitute a monophyletic group that is here proposed as a new genus. Derived traits of the transverse process of the fourth vertebra, postcleithral process and head laterosensory system support a sister group relationship between Horiomyzon and this new genus, indicating that a single miniaturization event occurred for this subgroup of heptapterids.

  • Life History Changes with the Colonisation of Land by Fish
    Life history changes with the colonisation of land by fish Edward Richard Murray Platt Supervised by: Terry Ord THESIS SUBMITTED FOR THE DEGREE OF MASTER OF PHILOSOPHY Evolution and Ecology Research Centre School of Biological, Earth and Environmental Sciences Faculty of Science University of New South Wales March 2014 THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Platt First name: Edward Other name/s: Richard Murray Abbreviation for degree as grven an the University calendar: MPhil School: Biological, Earth and Environmental Sciences F acuity: Science Title:Mr My thesis addressed two questions: whether survival was inferred to have improved for fish that moved onto land, and what the relative role of predation and density were for detenmining life history variation among populations within one of these land species. For the first question I used life history theory to examine whether survival was inferred to have improved in two fish families which have independently made the transition onto land: Gobiidae and Blenniidae. I examined growth and various aspects of reproductive investment among terrestrial and aquatic species, finding that differences varied according to the level of independence from water. This was consistent with improved survival for certain age classes on land. Nevertheless, the details of life history change differed in each family, with the greatest increases in survival implied for early age classes in Blenniidae, but older age classes in Gobiidae. This suggests fundamental differences in the way the colonization of land occurred in each family. For the second question I investigated the consequences of predataon and density on life hastory variation among frve populations of the Pacific leaping blenny A/ficus amoldorum.

    Martin LIFE SCIENCE Beach- Spawning Beach- Fishes Fishes Beach-Spawning Spawning Reproduction in an Endangered Ecosystem Beach-spawning fishes from exotic locations on most continents of the world provide spectacular examples of extreme adaptations during the Fishes most vulnerable life cycle stages. The beauty, intriguing biology, and importance of these charismatic fishes at the interface between marine and terrestrial ecosystems have inspired numerous scientific studies. Adaptations of behavior, physiology, development, and ecology are Reproduction in an gathered together for the first time in this book. Beach-Spawning Fishes: Reproduction in an Endangered Endangered Ecosystem Ecosystem serves as a comprehensive guide to beach spawning, a charismatic animal behavior that is seen in a surprising number of teleost species. This unexpected form of reproduction provides a window into the ecology of coastal areas, the behaviors and physiology necessary for fishes and their eggs to adapt to terrestrial conditions, and the threats and challenges for conservation and management. Beach-spawning species include important forage fishes such as the capelin, exotic fishes such as the fugu puffer, and the spectacular midnight runs of the California grunion. K21560 Karen L. M.

  • A Locomotor Innovation Enables Water-Land Transition in a Marine Fish
    A Locomotor Innovation Enables Water-Land Transition in a Marine Fish Shi-Tong Tonia Hsieh*¤ Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts, United States of America Abstract Background: Morphological innovations that significantly enhance performance capacity may enable exploitation of new resources and invasion of new ecological niches. The invasion of land from the aquatic realm requires dramatic structural and physiological modifications to permit survival in a gravity-dominated, aerial environment. Most fishes are obligatorily aquatic, with amphibious fishes typically making slow-moving and short forays on to land. Methodology/Principal Findings: Here I describe the behaviors and movements of a little known marine fish that moves extraordinarily rapidly on land. I found that the Pacific leaping blenny, Alticus arnoldorum, employs a tail-twisting movement on land, previously unreported in fishes. Focal point behavioral observations of Alticus show that they have largely abandoned the marine realm, feed and reproduce on land, and even defend terrestrial territories. Comparisons of these blennies’ terrestrial kinematic and kinetic (i.e., force) measurements with those of less terrestrial sister genera show A. arnoldorum move with greater stability and locomotor control, and can move away more rapidly from impending threats. Conclusions/Significance: My results demonstrate that axial tail twisting serves as a key innovation enabling invasion of a novel marine niche. This paper highlights the potential of using this system to address general evolutionary questions about water-land transitions and niche invasions.

Predator-induced defenses include changes in activity and body form in response to alarm cues. The response entails a trade-off between crypsis and sustained swimming to evade pursuit. We exposed four-month- and six-month-old sibling Nicaragua cichlids from two different broods to alarm cue (conspecific skin extract) to test for a change in swimming performance. Distilled water was the control for cue delivery, and green swordtail (Xiphophorus hellerii) skin extract was the control for a response to any injured fish. Depth, standard length, and total length of siblings in all groups were equal prior to treatment. After at least four weeks of odorant treatment, individual fish were subjected to stepwise increases in current velocity in a flume until they fatigued (maximum trial time = 14 minutes). The time and velocity at fatigue was used to calculate critical swimming speed, a measure of swimming performance. The critical swimming speed of fish exposed to conspecific alarm cue was lower than those exposed to distilled water (Mann Whitney Us, P < 0.05).
